Batman: Arkham Asylum is set to release later this summer, and Eidos keeps the hype train going by releasing a new trailer for the game. There were videosreleased previously that focused on some of the villains that we’ll be fighting in Arkham Asylum, but this latest trailer puts all of them in a nice, neat, little package with their names and aliases stamped next to their ugly mugs (ok, except for Poison Ivy).

According to this trailer, it looks like the villain line-up will be The Joker, Poison Ivy, Killer Croc, and Bane with Harley Quinn thrown into the mix. With those characters announced, do you guys think anyone else will possibly make an appearance in Arkham Asylum? My money would be on The Riddler possibly making an appearance as he was one psychotic character, and with the dark atmosphere that’s present in Arkham Asylum, he’d be a perfect fit.
